To all whom it may concern:

zen of the United States, residing at Cleveland, inthe county of (,fuyahoga and State of Ohio, have in\.f'cntcil certain new and useful Improvements in (las-Burners, of which the following is a specification, reference be- 'ing had therein lo the Aacconxpanying rection is across the arm. All of t drawing.

This invention relates to improvements in gas burners, the object of which is to-make a burner which prmluffes a flame that has a continuous rotation below and against the bottom ofhthe utensil, and because of this rotary movement, the flame is concentrated under the utensil and prevented from spreading andA escaping around the side ofthe utensil, .whereby there is a continuously moving live flame engaging the under surface et. the utensil, which increases its heating efliciency; in contra-distinction to the ordi- .nary fiame which strikes the bottom of the utensil at right angles thereto, which in practice rebounds and spreads around the utensil, and thereby causes part of the flame to escape, and a proportionate loss in heating efficiency.4

In the accompanying drawings, Figure l, is a side elevation of a burner embodying the present improvement, showinfr thereover va utensil, and illustrating the amc. Fig. 2, is a. top plan View of the improved burner, the direction ,of the flame being illustrated. Fig. 3, is a perspective view of the improved burner. Fig. 4, is a transverse, sectional view through one of the arms of the burner, am through one of the gas exit openings.

In carrying out the present inventionka burner of the star type is used, and as here shown, consists of a plurality of hollow arms l, which are in communication at their inner ends, and with the gas mixing tube 2, in the usual well known, and well'understood way` f 'lhe'present `improvement consists in pro viding the arms with gas exits 3, all of which extend therefrom at an incline, the angle of incline being preferably about fifty-five degrees. This angular arrangement is specifically illustrated in Fig. 4, and from which it willbe seen that thel an ular die open` ings in the arms are arranged in the same khorizontal plane, land all are inclined up-.

`the, utensil, and indeed l ward at the same angle, which prevents the 55 Be it known that I, HENRY llUrrnL, a cftispects a circle around the burner, and in 65 practice produces a rotary flame under and against the bottom ofthe utensil, and this circular' action tends to, and does largely concentrate the flame against the bottom of the utensil, and prevents it from escaping around` it as it does with a burner having the usual perpendicular gas escape openings. This action is found in practice to increase the 'heating efficiency of the burner, and. to prevent the over-heating prevents melting them loose as often happens with the Aordinary burner.

In order to produce the rotary action of the flame it is essential that all the liames 80 must extend from the arms 1, in thc same direction as respects the arc of a circle around the burner, as illustrated lin Fig. 2.

Referring to Fig. 2, it will be seen that thereby 60 This of the handles rof taking any one arm of the burner, the flames issue therefrom in a direction toward -a suc-v ceeding arm, and in a direction away from a preceding arm, all'of them extending in the same general circular direction as respects the burner. tary motion of the flame' where they mingle under and against the bottom of the utensil.

It is known that a moving ame: (such asa blow pipe action) is hotter than a comparatively quiet flame, sets up a rapid 'rotary flame under and against the bottom ,of the utensil"`with, its consequent heat generatin advantages, in addition to holding the ame thereunder and preventing it `from around the utensil. In the ordinary bottom of t rebound and escape, proved arrangement the reboundin not occur, because the flames strike t e boti ,gom of the utensil at angles all of which are burner with perpendieular gas esca e openings, the fiame strikes tlm' e utensiland has a tendency; g Whereas with this l0 This arrangement sets up a roand this arrangement escaping from walls und lower outer walls contractingl"1 'oin un iulerinediute point, 3.
